APPARATUS FOR ROLLING GLASS.

Specification of Letters Patent. Patented Aug, 23-, 1910. Applicationfiled May 3, 1909.

Serial No. 493,479.

To all whom it may concern:

Beit known that I, ANTON MEYER, a citizen of the United States ofAmerica, residing in the city of St. Lou1s,-1n the State of Missouri,have invented certam new and useful Improvements in Apparatus forRolling Glass, of which the followin is a full, clear, and exactdescript on, re erence being had to the accompanying drawings, formingpart of this specification.

My invention relates to an apparatus for rollin what is commonly knownas wire glass, or, in other words, plates of glass having embeddedtherein sheets of wire fabric.

In rolling plates of lass of this description, it is necessary to firstroll one layer of glass, apply the sheet of wire fabric above the layerof glass that has been rolled, and finally roll a second layer of glassonto the first layer above the sheet of wire fabric. In producin wireglass by following the procedure referred to, it is the usual practiceto utilize a carriage having a table on which the glass is rolled, aleading roll operating above the table by which the first layer of glassis rolled, and which is cooperable with the carriage, and a followingroll cooperable with the carriage located ata greater elevation than theleading roll, and which performs the oflice of rolling the second layerof glass. It has been the prac-' tice heretofore to support the leadingand following rolls upon runway members C0111- mon to both, carried bythe table carriage, and to operate these rolls by means in part commonto both of them carried by the table carriage; and further in order thatthe leading roll may operate more closely to the glass supporting tablethan the following roll to recess the end portions of the leading rollthat operate upon the runway members. The recessing of the ends of theleading roll, for the purpose stated, has been found to be anobjectionable feature in wire glass rolling apparatuses for the reasonthat it occasions a difference in the peripheral speed of travel betweenthe central glass working body of the leading roll and the recessedsupporting ends of the leading roll due to the difference in circum-=ference between the glass working body and l the supporting ends of theroll, as a result of which a drag ing action of the working body of theleading roll upon the first layer of glass and consequent faultyproduction of said layer, such as would not be produced in the absenceof said dragging action.

The prime object of my invention is to produce a glass rolling apparatusin which the leading roll and the following roll are supportedindependent of each other through the medium of the table carriage ofthe apparatus, and to provide for both the leading and following rollspartaking of the same peripheral speed at their glass working bodies asat the supporting portions, whereby dragging action of either roll uponthe glass being worked is eliminated.

Figure I is in part a side elevation and in part a vertical longitudinalsection of my glass rolling apparatus, portions of the frame of theapparatus being broken out to afford a view of parts back of them. Fig.II is an enlarged end elevation of the apparatus, viewed at its end atwhich the following roll is supported.

In the accompanying drawings :1 and 2 designate standards arranged inpairs at the sides of my apparatus.

3 designates a carriage having track wheels 4 that are adapted to rideupon rails 5 in order that the carriage may be moved longitudinally inthe apparatus. The carriage is provided with a table 6.

7 designates a leading roll that is rotatable above the carriage table 6and which is provided with spindles that are mounted in boxes arrangedfor vertical movement in the standards 1. The spindles of this roll havefixed thereto spur wheels 8, one of which is shown in Fig. I, and whichare cooperable with operating memberscarried by the carriage 3, as willhereinafter appear.

9.designates a following. roll, the spindles of which are seated inbearing boxes that are loosely arranged for vertical movement in thestandards 2 and have fixed thereto but spaced from the ends of thefollowing roll 'spur wheels 10 arranged to cooperate with the same rolloperating'carriage carried members that operate the spur wheels 8 of theleading roll 7 The spindles of the followin roll also have fixed to themoutside of t e spur wheels 10 and vspaced from the latter rollers 11that are of the same diameter as the diameter of the working body of theroll and which, by operating upon runway members carried y the carriage3,

v and to be hereinafter more particularly mentioned, serve to supportthe followin roll in a manner to provide for the body 0 said roll movingwith the same peripheral speed as that partaken of by the rollers in theoperation of the apparatus.

12 designates stepped rails fixed to the carria e 3 at its sides andwhich project laterafiy from said carriage to points beneath the rollers11 associated with the followin roll 9.

'13 esignates rack bars fixed to the carriage 3 and preferably arrangedupon the lower steps of the stepped rails 12. These rack bars extendlongitudinally of the carriage 3 and are so positioned 'as to be engagedby the spur wheels 8 and 10 associated with the leading and followingrolls 7 and 9, in order that when the carriage is moved on the trackrails 5, rotation will be imparted to both of the rolls through theinstrumentality of said parts.

The table 6 on the carriage 3 has mounted thereon trangs 14 that extendlongitudinally of the carriage and serve as supports for the leadingroll in order that it may be maintained at the proper elevation abovethe surface of the table to roll or spread an initial layer of glass.The leading roll is of the same diameter throughout its length, andconsequently when said roll partakes of travel while supported by thetrangs 14, its middle portion that operates upon the glass placediuponsaid table between said trangs moves with a peripheral speed the same asthe peripheral speed partaken of by the end portions of the roll thatride upon the trangs.

15 designates trangs arranged upon the upper steps of the stepped rails12 and which serve as runway members for the rollers 11 associated withthe following roll 9. These tran s 15 are of sufficient height to upholdthe f bllowing roll at an elevation sufiiciently above the elevation atwhich the leading roll is. supported to provide for the following rolloperating independently of and above the leading roll to spread thesecond layer of glass, after the first layer of glass has been spread bythe leading roll.

In the practical use of my apparatus, the carriage 3 is first moved to aposition that will cause its end indicated by a, (Fig. I), or theportion of the table on the carriagev on which the first batch of moltenglass is to be laid to be present in front of the leading roll 7 whenlaced upon the table. The batch of mo ten glass from which the firstlayer is to be produced is then de osited on the carriage table and saidtab e is moved in the direction of the arrow, Fi I, during whichmovement the leading ro acts to roll or spread the glass and produce thefirst layer of the plate of wire glass. Simultaneousl with this action,the wire fabric indicated hy the letter X is fed beneath the leadingroll and becomes impressed into the first layer of glass. A second batchof molten glass is then placed upon the first layer and the wire fabric,in front of the following roll, and this second batch is, during themovement of the carriage, rolled or spread by the following roll tocomplete the plate of wire glass. During these operations, the leadingand following rolls operate independently of each other, and due to thedescribed constructions of the parts providing for the support of therolls independently of each other, and the arrangement whereby the glassworking bodies of the rolls move with the same peripheral speeds as theroller supporting portions of the rolls, there is uniformity of actionby the rolls upon the glass and absence of any dra ging of the rolls, asa consequence of whic the liability of the occurrence of flaws in therolled glass, due to uneven rolling effect, is eliminated.
